In this .101 and the annexed drawings, 1' wit-ate the invention. in the lorm uh isider the best; but itnet I do not limit myself to 4 use the said invention may ied in other fo ms. It is also to ood that in by the claims tole d '3. herein, 1 do This invention relates particularly to moiuitingslor casement windows, although it is adaptable to other also.

In detail theiconstruction illustrated in the drawing includes: the Window frame composed of thexsill i and the lintel 2 oined by the side stiles 3 and 4 in the usual manner. The interior of the Window opening provided with stops 5 at the sides and top and the stool 8 across the bottom of the opening. The exterior is provided with the stops 6 at the sides and top, and the sill l at the bottom The sill 1 is grooved longitudinally as shown in cross section in Figs. 1 and 4. The groove 9 and rabbet 10 are spaced apart to leave the guide head 11 extending across the sill longitudinally between the side jambs 3 and 4. The sliding plate'has the central channel 12 slidably engaging the head 11. The upturned edges 13 and 14 of the sliding plate form the runners 15 and 16 sliding freely within the groove 9 and rabbet 10.

The sash comprises the top and bottom rails 17 and 18 oined by the side stiles 19 and 20, forming a rectangular frame to receive the glass 21. The sash is vertically pivoted in the opening on the lower pivot 22, having the sliding shoe 23 attached thereto and slidab'ly enga ing the central bearingplane 24 of the s iding plate, the flanged edges 25 of the shoe 23 preventing lateral displacement of the shoe, in its move ment on'the plane 24. The ivot 22 is move able vertically in a hole in t e bottom of the sash rail 18, provided with a. sleeve 26 fixed therein and revoluble on the pivot 22. The shoe 23' is maintained in contact with the plane 24 by the spiral spring 27 interposed between the ends of the pivots 22 and the bottom of the hole in the sash. The top rail 17 of the sash is vertically pivoted and guided in the lintel 2 by the pivot 28 movable in the sleeve 29 fixed in the top rail of the sash. The pivot 28 is provided with the shoe 30 attached thereto and slidable in a slot guide 2 formed longitudinally in the hotel 2 This shoe is forced against the lintel by the spring 31 confined betwwn the end of the pivot 28 and the bottomiof the hole in the top rail 17. These spr ngs 27 and 31 createthe necessary friction to aid in holding the sash in the desired adjusted positions. The weather strips 32 and-'33 res )ectively fixed in the top and bottom rails l( and 18. and {Rejecting beyond'theaface of the sash, engage rooves formed ill' the contiguous frame wor of the casement. It

is thefunction of these-strips in engagement with the casement to act as weather strips to exclude the weather or moisture who the port of the weight of the sash on the si performs the sonic function. The strip 3'1:

is adjustable laterally in a groove{fin-med in the side janib 4- and securelyj'nai-led therein after having been. propeiifv"adjusted to always meet the groove 86 in. thefledge oi the sash when the sash is. closed. The opposite side rail 19 ei'igages the groove 37 in the eide jamb 4, fitting snugly against the stop 38 to form a weather tight joint on this side oi? the sash in its engagement with. the frame. llie corners of the sash are cut away as at 39 to permit that edge of the sash to swing into the closed and reversed position.

The pivots 22 and 28 are set into the sash. stile as near the-outer edge as practicable (see .Fig. 2) and permit the sash to swing horizontally in an are from the stool o'uh Ward over the sill. To permit the reversal of the sash within the easement the shoe lit in the on the top pivot is permitted. to slide guide groove 2" provided for it in tin lint 1.. and the shoefiiion the notion; pivot is n mitted to move the sill, as; will he hereinafter more fully described. To control the movement of the sash across the case ment, the a'rmslO is-=provided (see Fig. The outer end of this control arm 40 is piv-- oted to the under side ofthe sash, outward a proper distance from the pivotalv edge of the sashgtheopposite end of the arm is pivoted on 4-1 on the adjustable plate 42 fixedv to the sill adjacent to one side of the case- Inent opening. The plate is gained into the guide'head 11 so that the underside of the arm is flush with the top of the guidewhen the sash is in the closed position. The arm. 40 is duplicated at the top of the sash to steady its movement.

The extended length of the sliding plate providee a large bearing surface for the sup h greatly facilitating the movement and sav lng wear on the Wooden portions supporting the weight. The metal shoe 23 bearing against the plane 24: of the sliding plate, is a metal-to-metal contact preventing undue wear and permitting free movementiof the sash, in that limited sector of the entire are of movement, at which the sash if most generally adjusted for ordinary vent lation. When the sash ismoved open-for reversal, the edge of the shoe. 23 engages the outturned lugs 43 on thesliding plate, by whichmeans the plate then moves forward with the shoe 23, until the sash reversed the de sired distance for the purpose of washing the outside of 'the sash, or directing the ventilation in the opposite direction so that the window-mae accommodated to meet the direction 0 the wind or other conditions. The return of the sash to the normal position slides the shoe 23 forward until it engages the similar lug 44 on the op osite end of the sliding plate, carrying'the utter forward until it abuts the side jamb 4 when as described in opening and cloieiing.

To prevent eli fiping or displacement oi the gliding plate on a flat sill as in Fig. 4;, the angular strip may be fixed to the sill. with the depending flange 416 overhanging the ui'itu'rned edge 13 of the sliding pie re =c Fig 4.).

"While I have shown and illustrated. casement having a single sash mounted therein, 1 do not wish to he understood as limiting this invention. to It is obvious that two sashes can he worked. in one casenn-nit by merely duplicating perte, in which event the meeting l and 50 of the sashes would he interlocked as illustrated in B, in which the flange 51 of one sash engages a groove 52 formed in the opposing sash to form an interldclied weatherproof joint. To facilitate the proper adjustment of the plate 42, I provide it with a slot 55 receiving the screw the plate until the de ired location of the pivots 41 is determin when the plate can be permanently fixed by setting a screw into the hole 57 in the plate.
